Hi all
I need to build a laser security circuit for a school project and was wondering if it would be possible to add a exit delay to my circuit so that there would be around 20 seconds to leave the room without triggering the alarm.
This is the circuit i have come up with so far... sorry i am a bit of a noob when it comes to electronics and any help would be much appreciated.
Thanks
